To add to Alan's comment about checking which database you are
connecting to, I have one:

In seems there are a couple of Java programs at work here, Hibernate and
the Spring Framework. I see something dealing with reflection and that
raises a flag.

Are you sure that the framework/Hibernate are doing the right thing?

pg_table_size accepts the OID or name of a table and returns the disk
space needed for that table, exclusive of indexes. (TOAST space, free
space map, and visibility map are included.)
